What a healthy turbo does for your BMW Série 3 320d
Behind the wheel of a BMW Série 3 (E46) 320d, 320 Cd or 320 td 150 ch, a turbocharger in good condition makes itself felt immediately: crisp pick-up from low revs, smooth and progressive boost build-up, and a complete absence of blue or black smoke under acceleration. A worn turbo, by contrast, shows up as a noticeable loss of power, an unusual whistling noise, increased fuel consumption and, sometimes, an illuminated engine warning light. Fitting a new turbo restores the original driving feel on this 2.0-litre Diesel engine, which is well known for its reliability when properly maintained.
Compatibility of the new turbo for the Série 3 E46
This new turbo is compatible with reference 11657790994, fitted to BMW Série 3 (E46) models equipped with the M47 D20 engine, whether in 320d saloon, 320 Cd coupé/convertible or 320 td estate form. Before placing an order, it is strongly recommended that you check the number on the label of your original turbo, as several turbo variants may exist depending on the vehicle's trim level and production period.
Straightforward sale – nothing to return
This new turbo is sold as a straightforward sale: a single delivery, no part to return, no collection and no deposit required. It is covered by a 12-month parts warranty, subject to fitting by a qualified professional. Payment can be spread over up to 10 instalments to make purchasing this technical component more manageable.
Common causes of failure on the M47 D20 engine
On this 2.0-litre Diesel engine, the main cause of turbo failure is insufficient lubrication, typically due to degraded or unsuitable oil, a clogged oil filter, or oil changes carried out beyond the recommended intervals. A blocked air filter or a cracked intercooler also disrupts airflow and accelerates blade wear. Consistently aggressive driving, without allowing the engine to warm up or cool down before switching off, places excessive strain on the turbo shaft and shortens its service life.
Fitting tips for a long-lasting turbo
Before fitting this new turbo to your Série 3, carefully inspect the oil circuit: check that the lubrication and return hoses are clean and unobstructed, and that oil pressure at idle is correct. Also inspect the air intake and induction circuit to rule out any leaks or foreign bodies. On first start-up, prime the turbo with oil before starting the engine, then allow it to idle for a few moments before raising the engine speed, to ensure optimal lubrication from the very first revolutions.
